Question

A man got a 10% increase in his salary. If his new salary is Rs 1,54,000, find his original salary.

Answer 1

we will say that his original salary is x

x+10x/100=154000

we bring to the same denominator

(100x+10x)/100=154000

we multiply with 100

110x=15400000

we divide by 110

x=140.000
